Raspberry leaf and other natural remedies

Hi ladies just wondering if you can give some advise as dr google has only brought up pregnancy stuff ( ie start taking from 32 weeks) but not much about early on.
I know evening primrose I need to stop when i O just wondering when do I stop taking the tea?

I did a lot of research before I fell pregnant and even spoke to the pharmacist and he also researched stuff for me and basically to have good periods that get rid of everything old you take Red Raspberry leaf for the whole period and from the start to ovulation take Vitex. It hurts really bad for the first cycle as every bit of old stuff comes out but you feel so much better after it.
